ABSTRACT:
A leaf spring is provided in which the major component is a leaf made up of continuous strands of fibers distributed in a matrix of polymerized plastic resin. The spring has a theoretical constant cross-sectional area and uniform width throughout its length and at the same time is thickest at its midportion and tapers to the opposite ends. The spring results in an arrangement having a cavity intermediate opposite ends and opposite sides which is capable of receiving locating pins or bolts of the type used with conventional metal leaf springs without the requirement for drilling of holes or otherwise weakening the structure. One embodiment of the invention incorporates a metallic leaf with the non-metallic components.
